Covariant LQG and spin foam quantization Auteur(s): Alexandrov S.
Conférence invité: QG2 2008 Quantum Geometry and Quantum Gravity Conference (Nottingham, GB, 2008-06-30) Ref HAL: hal-00326622_v1 Exporter : BibTex | endNote Résumé: After a brief review of a covariant approach to loop quantum gravity and of important notion of projected spin networks, I revise the spin foam quantization procedure of 4-dimensional general relativity. In particular, I discuss how the simplicity and the closure constraints should be implemented and demonstrate the precise agreement between the canonical and the path integral quantizations at the kinematical level. |
